Etymology

The compound "two-year" combines the numeral "two," derived from Old English "twā" (related to Proto-Germanic *twai), and "year," from Old English "ġēar" (Proto-Germanic *jērą). The hyphenated form emerged in Modern English to clearly denote a two-year duration, commonly used in contexts like "two-year contract" or "two-old child." The structure reflects a straightforward numerical-time relationship, preserving the original spellings of both components.
